To all Lwhom it may concern:

Be it known that I, JOSEPH Lenin. a citizen oii the United States ofAmerica, residing at San Quentin, in the county of Marin .and lStatie ofCalifornia., have invented cerltain nent/'a d useful improvements inConibination-P dlocks, of which the following is aspecificationilreference being had therein to the accompanying drawing.

rl`his inventionv relates to combination padlocks, and the principalobject of the same is to provide means which will facilitate theoperation of the lock'and reduce the wear upon the working parts.

In carrying out, the objects of the .invention generally stated above itwill be Winderstood. of course, that the essentiahjtfeatures thereof arenecessarily suscept1 ble of changes in detai'ls and structural'arrangements. certaiil preferred and practical embodiments of which areshown in the accompanying drawings, wherein Figure lv is a view invertical section of a padlock constructed in accordance with thisinvention. Fig. 2'is a top plan view. Fig. 3 is a view partly in sideelevation and partly in section of the operating pin and antifrictionrollers. Fig. el is an end view of the. devices shown in Fig. 3. Fig. 5is a detail perspective view of one of the tumblers of the padlock.detail sectional view thereof.

Referring to said drawings, it will be seen that the improved padlockcomprises a frame the base l of which carries theangular end bars 2 3.Said bar 2 has its free end portionprovided with' a longitudinal recessel which is intersected by a transverse opening 5. T he other end bar isprovidfd with a pivot ear G at its free end to which one end of ashackle 7 is pivotally connected. The other end of said shackle isadapted to be fitted within recess 4 of bar Q and is provided with atransverse opening H that alines with opening 5 of said recess l. -llndbar Il is provided with an intermediate transverse opening 9 that is inalinement with the opening 5 of bar 2 and through which a pin l0 extendsthat is adapted to pass through opening 5 and enter opening t5 ofshackle 7 to lock said shackle to bar 9.. lin l() is provided with asuitable finger grip l1 and an abutment flange l2 which Lto release pix`F ig. 6 is an enlarged` limits the movement of said pin in onedirection. Said pin is also provided with a longitudinal row of seats 13for the antifriction rollers '14.

The pin l() is retained in a shackle locking or unlocking position b'vthe tumblers l5 which are arranged to form combinations which arenecessary to complete before the pin can be moved to engagement 'with orbe disengaged from the shackle 7.

Said tumblers are lof the saine construction and are mounted on pm l0between the end bars 2 and 3. The .tumblers are preferably in the formof disks provided with a cen-A tral transverse counterbored opening 16with which a lateral opening 17 communicates. v

An abutment stop 'l5 extendsthrough bar 3 and is in the path of movementof the rolle-rs lai of pin l() and thereby limits the outward movementof said pin. Said stop is preferably in the form of a removablescrew,.\vhich Inav be removed when it desired to remove the pin l07 suchfor eX- ample to permit .the tumbler-s to be interchanged to permit letifonabination to be changed.

it will be sec Ltroni the foregoing that in shackles T, the openings 17of the tumbler-s must be in alinement to permit the rollers i-l of .saidpin to be moved therethrough. it will also be clear that the use ofrollers facilitatesthe operation of the lori; and prevents wear on theparts thereof.

lVhat I rlain: as in v invention iszl. i combination padlock comprisinga frame, a .shackle thereforf pin movable in said .frame and controllingthe locking of said shackle to said frame, rollers carried by said pin,and ine-ans supported b v said pin adapted to engage said rollers tonormally prevent said pin being moved to a shackle-releasing position.

2. 1i combination padlock comprising a base. a shackle therefor. a pinslidabie in said base and controlling said shackle7 antifriction rollerscarried by said pin. and combination tumble s carried by said pin andadapted to engage said rollers to prevent the said pin being operated.

3. A combination padlock comprising a frame, a shackletheret'oi.provided with il v 5 combination tumblers carried by lsaid pin recessin its free end, a pin 'slidable in said base and adapted' to engagedthesaid recess signature in presence of two Witnesses.

to lock the shackle to sai frame, anti- 1 y friction rollers carried bysaid pin, andi JOSEPH LORLX' In {estimoy Whereof I hereunto aix my Witnesses:v and adapted 'to en age said rollers to pre- DANIEL SULLIVAN,vent the said pin elng operated. J. H. MURRAY.
